Demand [for the new iPad] has been incredibly robust. We are selling them as fast as we can make them, as Peter mentioned earlier. In China, I believe on a macro basis, China has an enormous number of people moving into higher income groups, middle class if you will. This is creating a demand for goods, not just Apple's but other company's goods as well. I think that there's a tremendous opportunity for companies that understand China, and we're doing everything we can to understand it and serve the market as good as we can.

Tough question to answer. Obviously we're aware of the transition issue you mentioned [regarding Qualcomm chips] with 28 nanometer. We currently do not use 28 nanometer parts, but as you also know we don't comment on future products, so I can't talk about the future part.

Generally, outside of this, we work very closely with our supplier partners, and do everything that we can do to get supply, and sometimes we're successful with that, and sometimes we're not. You can bet that we are focused on anything that we think may impact us in trying to push every button within our disposal to work on it.
